A1 and A4 motorway repairs in Silesia — removing "Danube waves" costs 700m PLN

A 700-million-PLN repair project is under way on the Silesian section of motorway A1 to eliminate so-called "Danube waves" — surface deformations that slow traffic. Road workers are simultaneously carrying out works on other fast roads in the region. Drivers should expect significant disruptions when passing through Silesia.
